Abstract

PURPOSE:To obtain a piezo-electric filter wherein symmetric damping characteristic can be obtained and moreover a sufficient guaranteed damping quantity can be obtained, even if the thickness of the square type piezo-electric bodies of the piezo-electric resonators connected in series with one another are made identical with one another.
